Well jokoo do, if you agree that pressure is the average of the finite energies of particles striking a surface and reject pressure as quantized is contradictory.
Not the average, the sum. More importantly, though, the sum of their energies striking a surface
per unit of time,
per unit of surface area. In order for pressure to be quantized, it's not enough for their energies to be quantized, time and space would have to be too. Even if we accept your claim that energy is quantized (not something you've demonstrated either), the conclusion that pressure is quantized is like saying "if you accept that the Netherlands are in Europe, your rejection of the conclusion that Europe's area is 41,543 km² (the area of the Netherlands) is contradictory".
As all Newtonian variables at a high enough density in the tank we treat pressure as infinitely divisible.
I can not do it off the top of my head I'd have to work on an equation. It requires statistical mechanics. Roughly the atoms in the tank are in continuous collisions with each other and the tank. Collisions with the tank transfer thermal energy to the gas. There is a probability of an atom hitting the tank at any point on the surface. The result will be a probability distribution defining how many atom strike an area of the tank at any instant.All particles may not have the same energy.
Rain falling on your car roof if heavy enough although quantized as drops will sound continuous. The total kinetic energy transferred to the roof is the sum of the drops each having finite energy.
Yes, and? Drops come at all kind of velocities, so in order to show that the kinetic energy is quantized, you still need to demonstrate that velocity is quantized. Depending on the local air density, they are slowed more or less by drag. Larger drops are generally less affected by air drag than smaller drops, and while drop sizes are multiples of one molecule of water, the relationship is non-linear. Furthermore, they don't fall as perfect spheres but are continually distorted by the same air drag during their fall, changing their shapes, and with it the amount of resistance and thus their velocity continually changes even given a certain air density, so even in one and the same spots, they'll be coming in at different velocities.
Only in a perfect vacuum, and then only if they've been released at the exact same vertical distance from whichever spot on your car they're going to hit* would the drops be all coming in at a fixed velocity, and thus their energy be determined by a linear relation to their mass, quantized as multiples of the mass of a water molecule.
How often do you park in a perfect vacuum?
You appear to lack imagination, unable to visualize.
Your arguments are specious at best. I don't run off and email others for support.
You can't have it both ways. If you accept atoms as having discrete mass and energy you can't reject that the force on the surface of a tank can only change in discrete multiples. Fill a tank with marbles, does the force on the walls and bottom vary continuously or in steps of the mass of the marbles and gravitational energy?
Gas pressure doesn't work like that, it's caused almost entirely by the molecules impacting the walls (bottom and lid included), with the weight of the molecules under standard Earth gravity being an all but negligible contributor to pressure at the bottom. It's true that the molecules' paths are, in theory, parabolic, and thus there'll be slightly more molecules near the bottom than near the top at any one time and the bottom will get slightly more hits than the top, but outside of an ultra-high-vacuum chamber at temperatures near absolute zero, a molecule will typically (that is to say, almost invariably) be colliding with another or the casing long before this deviation from a linear path becomes apparent.
But assume a closed tank with the marbled packed so tightly that they're pressing not only against the bottom and the sides, but also against the top: The pressure will indeed vary continuously e. g. if you add heat to the setup: depending on whether whatever material the tank is made from expands more or less under heat than glass, pressure will decrease or increase with temperature; or if you move in the walls, reducing the size of the tanks along continuous space, pressure will increase continuously.
* To be precise, not even then: consider a droplet that has been released 100 meters above your hood, thus say 101.0 meters above ground, and one that's been released 100 meters above your roof, or 101.5 meters above ground. Considering that gravity diminishes with distance, one of them will have been accelerated more than the other throughout its journey, and thus have a higher velocity at impact even in a perfect vacuum. So in order for your conclusion that the impact energy is quantized because water drops are quantized to follow, not only do we need to assume a perfect vacuum, but also we'd have to pretend that gravitational acceleration is altitude-invariant.
